Decimated, but not down. Or defeated.

COVID-19 couldn’t stop the Nets. Apparently neither could Toronto.

Despite playing without nine players — seven of them due to NBA health and safety protocols — the Nets rallied for a 131-129 overtime win against Toronto before 17,325 at Barclays Center on Tuesday night.

They had just eight active players — the league minimum — and only one of their Big 3. But they made sure it was enough, with Kevin Durant — questionable with a sore ankle — refusing to sit out, which would have forced a postponement. The last star standing wouldn’t miss the game, and he wouldn’t let the Nets lose it.

“I just try to do what’s required, man. I want to be out there, I want to play, I want to win. So whatever I got to do to accomplish those three things I’m going to do,” Durant said.

“It’s December and we’re down seven players and we easily could’ve punted this game. … But we saw an opportunity for us to grow and get better — especially the young guys.”

Durant had a triple-double with 34 points, 13 rebounds and 11 assists, while Patty Mills added 30 points — including 19 in the fourth quarter and overtime. Mills played alongside four rookies in the second quarter, as Durant did in the third.

The East-leading Nets (20-8) were without Kyrie Irving, Joe Harris, James Harden, LaMarcus Aldridge, Bruce Brown, DeAndre’ Bembry, Jevon Carter, James Johnson and Paul Millsap — the latter seven all due to positive or inconclusive COVID-19 tests. But the Nets refused to quit.

“Incredibly proud of these guys. They had every reason to find a way out, especially at the end when they’re exhausted and they got in a little rut, Toronto had momentum,” Steve Nash said. “They didn’t fold. They never gave in, they found a way to stay in the game even when it was difficult.”

Mills had 13 points in an 18-4 fourth-quarter run, turning a 107-99 deficit into a six-point edge. And after the Nets squandered it, his huge 3-pointer with 13 seconds left in regulation forced OT. That’s where he and Durant won it.

Chris Boucher and Pascal Siakam put Brooklyn in a 124-120 hole, but Durant hit three straight buckets to dig them out and put them up by two. And Mills’ 16-foot baseline pull-up made it 128-124 with 2:08 left.

Gary Trent Jr.’s layup cut the lead in half, but the Nets forced three straight Toronto misses, two by Fred VanVleet (31 points). But rookie David Duke Jr.’s offensive rebound and two free throws with 10.3 seconds left gave the Nets a 130-126 edge.

VanVleet’s 3 with four seconds remaining made it nervy, and Mills sank just one of two free throws to leave the Raptors a chance. But Scottie Barnes’ last-ditch 33-foot heave missed, and the Nets had the unlikeliest of victories.

The Nets relied on youngsters like Nic Claxton (16 points), Duke (10 points, 13 rebounds) and rookie Kessler Edwards (17 points, 10 boards).

“There was a moment where I looked at [player development coach] Tiago [Splitter] and was like, ‘Do I put on my shoes now? What’s the deal?’ ” Mills said. “But that transformed into a conversation within the room, like, we’re here now: Let’s roll the ball out and have fun and let’s hoop.”
